The Japanese blog Egami found a new Sony patent that describes the characteristics for two new standard lenses. A new 50mm f/1.2 and a new 50mm f/1.4 fullframe lens. Those are the specs:
- Patent Publication No. 2011-107450
- Published 2011.6.2
- Filled 2009.11.18
- Embodiment 1
- Focal distance f=49.98mm
- Fno=1.442
- Half angle of view 23.73 deg.
- Asph. 1
- Embodiment 2
- Focal distance f=51.54mm
- Fno=1.443
- Half angle of view 23.17 deg.
- Asph. 0
- Embodiment 4
- Focal distance f=51.55mm

I guess that those would be welcomed updated of the current 50mm f/1.4 from Sony. Check the specs and price of that lens by clicking those direct links: [shopcountry 7134]. A new and well praised alternative is the Sigma 50mm f/1.4 which you can get at [shopcountry 6765].
